We may consider other design concepts, but we will probably stay with the above unless something truly exceptional comes along.

The "X" can be in red, electric blue or electric green.
The "F" can be a similar design to theirs but not identical as don`t want people to think we`ve totally copied their logo. The "GRANDPRIX" can be a different font to the "FX". It can either be in all uppercase, or the "G" and "P" in uppercase, whichever looks better.
